Active galaxies are thought to be powered by?
Active Galaxies are thought to be powered by rotation
How are black holes involved in understanding active galaxies?
It is difficult to ask black holes about how they are involved in active galaxy research because they cannot talk, this makes them only peripherally involved in understanding active galaxies
What are the release dates for Astronomy Observations and Theories - 2005 Active Galaxies 1-14?
Astronomy Observations and Theories - 2005 Active Galaxies 1-14 was released on: USA: 21 June 2006
How are scientist able to identify the different types of galaxies?
The scientists are able to identify the different types of galaxies by high powered telescopes and by examining the pictures sent by various satellites orbiting the universe.
What is a young galaxy with a giant black hole in the center called?
quasar
How is know that active galaxies have small core regions?
It is known that active galaxies have small core regions because we can see them in images! These small regions known as uassars emit perful amounts of both radio waves and gamma rays...
How do scientists categorize galaxies?
Scientists categorize galaxies based on their shape and structure into three main types: elliptical, spiral, and irregular galaxies. Elliptical galaxies are smooth and featureless, spiral galaxies have distinct arms winding out from a central bulge, and irregular galaxies lack a defined shape. Additionally, galaxies can be classified by their size, brightness, and the presence of active galactic nuclei. This classification helps astronomers understand the formation and evolution of galaxies in the universe.
What are distant galaxies with black holes in their centers called?
There have been some suggestions that the objects called quasars might be extremely active galaxies with unusually supermassive black holes at their centers at such great distance from us that it is not possible for telescopes to resolve their galactic structure, making them just look like very bright stars (quasi-stellar objects). However this has not been verified.If these suggestions are correct, these extremely active galaxies must be so distant that the light we are seeing from them must have been emitted only a short time after the big bang began, in the initial cycle of star formation, which would make them the earliest galaxies formed and likely very young galaxies. However if they are this young these extremely active galaxies might have galactic structures so different from the galaxies we are familiar with that even if our telescopes could resolve them, we might not recognize them as galaxies.
What do active galaxies differ from normal galaxies?
Galaxies that emit much more radiation (different types of radiation) than a typical galaxy. This actually happens in the galaxy's center, so it's more accurate to talk about an active galactic nucleus. The active galactic nucleus is believed to be caused by a black hole. From Wikipedia: " The radiation from AGN is believed to be a result of accretion of mass by a supermassive black hole at the centre of its host galaxy."
What is the difference between active load and passive load?
Passive Load is Load comprising of Passive Components Active Load is the Load comprising of Active Components In Test Boards its better to use Active Loads, If you are concerned about Temperature Variations during characterisation
What galaxies have mostly old stars without a lot of active star formation?
The milky way. and if this is incorrect I'm sorry. and if it is right like my answer please?
What is the difference between an active antenna and a standard antenna?
An active antenna has a amplifier built in, a standard antenna does not. AKA powered antenna.
